yo2001 Posted December 3, 2003 Share Posted December 3, 2003 I changed the plugs today on my L26ET (2.6L). while I was working on it, I found my plugs that I got are not projected tip like my old ones? Is that a bad thing, it's on a turbo car. Thanks Quote Link to comment Share on other sites More sharing options...
Guest bastaad525 Posted December 3, 2003 Share Posted December 3, 2003 From what I understand, projected tip plugs are better for and should be used with fuel injected engines, and the short tip plugs are for carbed cars. I've used either in the other kind of engine and did not notice any detrimental effects, however, there's gotta be a reason for it...

SpeedRacer Posted December 4, 2003 Share Posted December 4, 2003 Projected tip spark plugs reach farther into the cylinder and are exposed to more of the incoming charge (air & fuel). It is also a longer path for heat to travel through the electrode, into the ceramic insulator, through to the spark plug housing and finally into the head finally the water jacket. This means that a projected tip plug will not only spark farther out into the incoming mixture for a better burn but, more importantly, it will have a much larger heat range. This is very important to help reduce the possibility of spark knock and, at the same time, help prevent spark plug fouling. Quote Link to comment Share on other sites More sharing options...
